I got my hands on a Google Earth OS X beta client a few weeks ago and it ran pretty well on my 12" 1GHz PowerBook. I’ll grab the release version and see what improvements it offers, and I’m curious to know how well it will run on Intel-based Macs.
Download Google Earth—choose your platform and view system requirements, and off you go.
What a cool week this is turning out to be technology-wise, geekily speaking. :-)
